Furnace Installation & Replacement in Brighton

At 4,987 feet, Brighton is one of the lowest cities we serve, but the altitude still costs about 20% of a furnace's sea-level rating. An 80,000 Btu/h input furnace works out to about 64,000 Btu/h here after high-altitude setup. We run a Manual J on every replacement. Production homes from the 2000s were often fitted with a single furnace size across a floor plan, so the right size for your house may differ from what the builder installed.

From January 1, 2026, a new gas furnace sold in Colorado must meet the 14 ng/J NOx limit or the current ENERGY STAR version. Since July 31, 2026 that is Version 5.0, which requires about 97% AFUE in the northern U.S. Your existing furnace is unaffected and can keep being repaired. When you replace it, every quote should name which compliance path the new model uses. We put that on paper.

Most 2000s homes in Brighton Crossing and Bromley Park already have a condensing furnace with PVC intake and exhaust. Replacing it with a 97% model is usually straightforward, but we still check pipe diameter against the new furnace's maximum vent length, confirm the sidewall termination isn't where snow drifts, and replace the condensate trap and drain line. Where an older home is moving from an 80% furnace to condensing, we price the new vent route and any change needed for the water heater's vent.

Furnace replacement in town goes through the City of Brighton's Community Development permit counter, and we pull the permit and schedule the inspection. If you have no heat, the city's rules let us install first and file the permit application no later than the following business day, leaving the work uncovered until the inspector signs off.

Gas comes from Xcel Energy, and electricity from United Power. That split matters if you are weighing a heat pump: Xcel's heat pump rebates apply to Xcel electric customers, so ask United Power about its current programs. The state's $1,000 air-source heat pump tax credit and the $1,500 cold-climate rebate from DRCOG's Power Ahead Colorado are separate from your utility. Our heat pump cost guide lays out typical metro pricing.
